Application ined october, 12,1925. seria; No. '62,02'4. t

This invention relates to improvements in ophthalmicmountings,andconsists more particularly of anew and novel'end piece or templeconnection.

l One of theprincipal objects of the present invention is to provide animproved hinge connection for securing the temples to theV lens vrimsand'for securing the lens rims together. Y ,v Y, I

' Another object of the invention is to provide such aconstruction'wherein the temple may be removed without disturbing thelcon' nection of the ends of the lensfrims, and' vice versa. v

Anotherv object isto provide such a construction wherein'the liability`of the lens rims becoming out of alignment with each other will beeliminated.

vAnother object is to provide an end piece construction that is strong,compact and neat appearing, that will retain its alignment, and truenessof working parts during the accompanying drawings, wherein Y Vis shownand described by way of'illustration one particular, practicalembodiment therel v the present invention; v

of, it being `apparent .that various modifications may be made` whichwill fall within the scope of the rinvention as set forth in theappended claims', 'all of which modifications are considered asy 'withinthe kspiritof the invention and forming a'partithereof` In the drawings,forming a part of .this

application, and in which similar characters are used to denotecorresponding parts throughout. Figure lisa front elevation of'a pair ofspectacles constructed in accordance with Figure 2 is an enlarged viewofthe end piece and temple securing means;

Figure 3 isa top plan view thereof; Figure 4is a sectional 'view on line1f-4 Y of Figure 2;

Figure 5 isa'view somewhat similar to Figure 2, showing' the differentparts'pr-ior to the assembling thereof. p

Referringnow to the accompanying drawings, there is shown a spectaclecomprising a pair of lens rims 1O connected together by means of asuitable bridge 11 and'sup- Other objects andvadvantages of the inventionl will be apparent from the followying specification taken `inconnection with lported the face, of the wearerby theitem! ples 12. Eachof the said lensrims is split VOLUNTARM 'Ass'ooIA-LV j" and terminatesin theseparated endpieces Y 1.3 Vand 14, 'said end pieces being ofsubstantially rectangular formation, and provided with the registeringopenings 15 and16.v

Arranged to enclose 'the -end pieces 13 and y 14, is a housingconsisting Vof the two parts 17 and 18, each of said parts being formedf ,i l.

with a recess 19 to receive-one vof thevsaid end pieces, the sides 2 0and 21 of the parts 17 and 18 respectively, overlappingthe ysides of theend pieces, and being slightly spaced 'l from each other, as atk 22, inorder that sufficient pressure may be applied thereto,

when securing the lens rims together byV means ofthe fastening screw 23whichpassesf" through registering parts and end pieces'.

The adjacent faces ofthe parts 17 and 18V are alsorcut away tokformatemple receiving recess 24 for the reception of the temple openings ine the said 12, said temple being pivotally mounted lon;

the fastening screw 25 passing `throughregf istering openings in thesaid parts.

In the assembling of thev invention, the two parts 17 andv 18 yare.firstr placed .over the Y' end pieces 13 and 14, after which ,thefas-Ktening `screw `23 'ispassed through thepregjL istering openings,-whereby` to' secure the, Y housing. and end pieces together land thelens rim in closed position. The temple the screwV 25 passed'therethrougln whereby to retain the same. in position.

From the above'it will thusjbeseen that there has been provided animproved'hinge*` Y connection ofthetype specified, which willV performall of the functions and accomplish all ofthe objects enumeratedhereinabove,"

and while there has been shown` and de- V12 is-then inserted withinthegreces's L24 and 1f 'scribed one practical embodimentofthe in- Y vvention, it will be understood that Vvarious modifications thereof maybe made without 4departingfrom or exceedingthespirit of the f l 100. f
